Vijay commented on CASSANDRA-2167:
----------------------------------
Initial Tests show better performance with this approach... BB.array is not
allowed for DBB and it wasn't clean and this approach seems to fit better with
the existing approaches.
> Add a deserialize(ByteBuffer) method to ColumnFamilySerializer
> --------------------------------------------------------------

> by adding deserialize bytebuffer in the columnFamilySerializer we might be
> able to avoid copying of the bytes[] while deserializing the CF.
> This can be done using....
> ByteBuffer buff = ByteBuffer.wrap(bb.array(), bb.position(), length);
> This is an improvement on
> "https://issues.apache.org/jira/browse/CASSANDRA-1969"; Plz see jonathan's
> comment.
